A method of transmitting, by a first terminal, information about a pre-coding matrix to a base station in a multiple node system comprises the steps: measuring a downlink channel of a first node through a reference signal for CSI (Channel-State Information) measurement of the first node; measuring a downlink channel of a second node through a reference signal for decoding transmitted by the second node; and transmitting, by the first terminal, information about a pre-coding matrix for the first terminal to the base station on the basis of the measured downlink channels of the first and second nodes.
